Collecting Stamps and Drinking Hot Chocolate as Spiritual Warfare

Screwtape exhorts his nephew:

I would make it a rule to eradicate from my patient any strong personal taste which is not actually a sin, even if it is something quite trivial such as a fondness for country cricket or collecting stamps or drinking cocoa. Such things, I grant you, have nothing of virtue in them; but there is a sort of innocence and humility and self-forgetfulness about them which I distrust. The man who truly and disinterestedly enjoys any one thing in the world, for its own sake, and without caring twopence what other people say about it, is by that very fact forearmed against some of our subtlest modes of attack. You should always try to make the patient abandon the people or food or books he really likes in favour of the "best" people, the "right" food, the "important" books. I have known a human defended from strong temptations to social ambition by a still stronger taste for tripe and onions.
